Hollow block system

Abstract

To create decorative border arrangements on the ground, a kit of blocks and interconnecting pieces is provided. To assemble the blocks end to end into a row, the opposite end faces of the blocks and the two opposite sides of the interconnecting pieces comprise respective mutually mating interconnecting elements extending transversely of the row and being slidable in each other upon transversal displacement of an interconnecting piece between the confronting end faces of a pair of consecutive blocks, thus fastening the two confronting end faces together. When desired, pickets are used to anchor the blocks to the ground to obtain a semi-permanent construction.

What is claimed is: 
     
       1. A kit of parts comprising blocks and interconnecting pieces to assemble said blocks end to end into a row, each block comprising two opposite end faces and each interconnecting piece comprising two opposite sides, said end faces of the blocks and said sides of the interconnecting pieces comprising respective mutually mating interconnecting elements, wherein the interconnecting elements of one of said interconnecting pieces mate with the interconnecting elements of the confronting end faces of each pair of consecutive blocks of said row to thereby fasten said confronting end faces together, wherein (a) each block has a longitudinal axis, (b) the end faces of each block define a predetermine acute angle 90°-α with the longitudinal axis of said block, and (c) each interconnecting piece is flat and comprises a tapered border defining an angle β=2α to fit between the confronting end faces of a pair of consecutive blocks of the row.   
     
     
       2. A kit of parts as described in claim 1, further comprising at least one cap plate member having one side provided with interconnecting elements, said interconnecting elements of the cap plate member and said interconnecting elements of each opposite end face of the blocks mutually mating each other to mount said cap plate member on one of said end faces of the blocks. 
     
     
       3. A kit of parts as described in claim 1, wherein said blocks are hollow and made of plastic material. 
     
     
       4. A kit of parts comprising blocks and interconnecting pieces to assemble said blocks end to end into a row, each block comprising two opposite end faces and each interconnecting piece comprising two opposite sides, said end faces of the blocks and said sides of the interconnecting pieces being provided with respective mutually mating interconnecting elements comprising hook members on said faces or sides and apertures on said sides or faces, respectively, said hook members being structured to slide in the apertures upon transversal displacement of one of said interconnecting pieces between the confronting end faces of a pair of consecutive blocks of said row to thereby fasten said confronting end faces together. 
     
     
       5. A kit of parts as described in claim 4, wherein said hook members comprise right angle hooks, and wherein said apertures are L-shaped to define therein respective rectangular projections to be hooked by said right angle hooks. 
     
     
       6. A kit of parts comprising blocks and interconnecting pieces to assemble said blocks end to end into a row, each block comprising two opposite end faces and each interconnecting piece comprising two opposite sides, said end faces of the blocks and said sides of the interconnecting pieces comprising repective mutually mating interconnecting elements, wherein the interconnecting elements of one of said interconnecting pieces mate with the interconnecting elements of the confronting end faces of each pair of consecutive blocks of said row to thereby fasten said confronting end faces together, wherein said blocks comprise (a) at least one first elongate straight block having two opposite end faces each provided with at least one of said interconnecting elements, (b) at least one second curved block having two opposite end faces each formed with at least one of said interconnecting elements, and (c) at least one third block square in horizontal cross section and defining two pairs of opposite end faces each provided with at least one of said interconnecting elements.   
     
     
       7. A kit of parts as described in claim 6, wherein said blocks are hollow, and wherein said mutually mating interconnecting elements comprise (a) right angle hooks formed on the opposite sides of each interconnecting piece, and (b) L-shaped apertures formed on said opposite end faces of the first, second and third blocks and defining therein respective rectangular projections to be hooked by said right angle hooks. 
     
     
       8. A kit of parts as described in claim 7, further comprising at least one cap plate member comprising one side provided with right angle hooks structured to be hooked to the rectangular projections of the L-shaped apertures formed on the opposite end faces of the first, second and third blocks.
